upper face or surface of the bolsterl to reV ceive a' coacting male member of a bearing on a cooperating body bolster, said recess,

pocket .or female member being formed by .a

separate element and seated lwholly lwithin the body and rigidly secured toy said bolster.

Second, to provide a hollow y'truckfbolster witha recess, pocket or female member of a bearing and capable of securing. said female membereto any dept-h within saidbolster without weakening the carrying capacityV of@` v said/bolster and furthermore reenforcing l Figure 1.

fthestrength 'of thebolster due to the thickness and uniform and proper distribution of vthe metal at the juncture of said'female bearing member `with the upper section or top ofk said bolster. f

- Third, to provide a hollow 'truck bolster of the character indicated .with a female member which can be made ofany depth without altering the llocation or point at which the load isV applied or carried by the bolster and the strength of'said bolster is not sacrificed by the depth or location of'said female bearing member. i Y

Fourth, to prov-ide :hollow/truck bolster with Va removable A andy renewable female bearing kelement extending into the body of the bolster and supported from the. upper face of said bolster, whereby a fractured or worn outbearingelement may be detached and another quickly substituted .therefor without discarding the other sec-tionsof the r.bolster as is common practice with the present type of truck bolsters.

Fifth, to construct a hollow or `boxed truck bolster ofcast or .pressed steel having a yfemale bearing member inserted into the body of the bolsterL and suspended from the top ofthe side walls and upper face `.ofthe bolster. v

Sixth7 to provide a construction and arrangement oftruck bolsterbetter adapted to be cast in steel and capable of greatly reduc- `thedif'iCulties of shrinkage, cracks or fracturesinherent and usually lmet .with in I the art'of ksteel casting.

Seventh, other objects and advantagesy of construction and arrangement of theyseveral elements comprising the truck bolster will be apparent from the detaileddescription-and manner of operation of the same.

' .The invention consists of structural char# acteristics and relative arrangement of .ele-

ments which will be hereinafter morefully .described andparticularly pointed out in the appended claims. n

Referring toFigures 1, 2 and 3 of the drawings, `10 is a'hollow or-boxed type of 'truckbolster preferably made of cast steel .andprovided jwith the top 11, ybottom 12,

sides. 13, 13, and ends 14, 14. n The top 11, oottom 12, sides 13, 13 and ends 14, 141, are

provided with openings 15, 15,16, y16, 17, 17 and 18,18, for the purpose of reducing the weight and costof manufacture of the bolster, land at thesaine time providing means for the removal of therbrokencores from ythe casting ofy said bolster.

The top 11 ,of the bolster midway between the ends 14, ltand sides 13, 13, is provided with a circular opening 19`in1which is lseated or supported wholly `within the hollow bolster a pocket or-female member ofa center `bearingQO, said member consisting prefer- .the-female bearing'member 2O enables V.the

Cil

same to be supported from the upper face 11 and-suspended from the top of the sides 13, 13 and flange of the truck bolster, thereby transferring and distributing the load on the body bolster 27 over the middle sec` tion of face or top 11 of the truck vbolster 10, and the project-ing flange 25 at the same time greatly strengthens and reenforces that section of the bolster which has been wealtened due to providing the opening 19 for the reception of said bearing 20.

Cooperating with the above described truck bolster 10 is a hollow body bolster 27 having rigidly attached to its under side by rivets 28 or other means, a downwardly projecting hollow male member 29 which is adapted tobe seated and supported in the pocket or female bearing member 2O of truck bolster 10 and permitting said body bolster 27. to properly and easily swing through a small arc, as required in this class of railway car appliances, and needs no further disclosure. The bottom and side walls of said hollow projecting male member 29 of,

the body bolster 27 are preferably provided with openings 30, 30, through which may pass anygrease or lubricant stored in said hollowmale member 29, said grease or lubricant passing into the center bearing 2O of the truck bolster 10 and between the con-l tiguous side walls and bottoms of the pocket or female bearing member 2() and male member 29, the grease being supplied to the hol- -low male member 29 through the opening 31 (see Figure 8) communicating with the interior of the hollow body bolster 27.l

ln Figures 4, 5 and 6 is shown substantially the same invention as described with reference to Figures 1, 2 and 3, except the truck bolster' 101 is made of pressed steel and consists, as shown, of top 111, bottom 121, sides 131, 131, and ends 141, joined together by rivets 132, 132, to form an elongated hollow or boxdike structure, the top 111 of which is provided with a central opening 191 in which is seated the pocket or female bearing member 201 removably secured by rivets 261 passing through the outwardly projecting flange 251 and top surface 111, in the same manner and for the purpose as hereinbefore explained.

The body bolster 271, shown in Figure 5, may be of the same construction and arrangement as that of the body bolster 27,

yshowin and described with reference to Figure 2, and needs no further disclosure. as to its detail construction or manner of cooperation with the truck bolster 101.

From the foregoing disclosure it will be seen that all the objects and advantages krecited in the statement of invention have been fully and eliiciently carriedoutand a cast or pressed steel truck bolster has been devised in which an independently removable pocket, recess, well, or female bearing `While I have shown and described the preferred forms of the invention, it will be readily understood that many changes and arrangements will readily suggest themselves without departing from the spirit of the disclosed invention or changing the function and cooperation of the elements as expressed in the claims. .v
